Steaming structure for a steam oven

Abstract

A steaming structure for a steam oven includes a housing having an accommodating groove and a draining hole communicating with each other. The accommodating groove has a connecting pipe connected with a water-pumping motor connected with a duct, which is connected with a water-feeding pipe positioned in the housing. An electric heating tray with a center hollow is installed below the water-feeding pipe. A regulating device is connected with an exhaust passageway of the housing having an exhaust hole. A holding tray with two accommodating chambers is placed in the accommodating groove of the housing. A water tank is received in one of the accommodating chambers. A cover plate is covered on the holding tray, having an insert hole aligned to the draining hole of the housing and located on the accommodating chamber.

1 . A steaming structure for a steam oven comprising: 
 a housing provided with an accommodating groove in its bottom and bored with a draining hole in its interior communicating with said accommodating groove, said accommodating groove having its inner wall provided with a connecting pipe, said connecting pipe connected with a water-pumping motor, said housing further provided with an exhaust passageway at the inner upper side, and an exhaust hole bored in a topside;    said water-pumping motor having the other end connected with a duct that has the other end connected with a water feeding pipe inserted in said housing;    an electric heating tray positioned below said water feeding pipe in said housing and formed with a center hollow opening upward;    a holding tray received in said accommodating groove of said housing and formed with two accommodating chambers; and,    a water tank received in one of said two accommodating chambers and bored with an inflow hole in an upper wall and an outflow hole in a rear wall, said outflow hole assembled with a sleeve connected with said connecting pipe of said accommodating groove at the bottom of said housing.    
   
   
       2 . The steam structure for a steam roaster oven as claimed in  claim 1 , wherein said regulating device is composed of a connecting base, a blocking member, a fixing base and a regulating button; said connecting base connected with one end of said exhaust passageway, said fixing base positioned at one side of said connecting base, said fixing base formed with an accommodating chamber having a through hole in the interior, said fixing base further bored with an insert hole in the center, said blocking member received in said accommodating chamber of said fixing base, said blocking member bored with a through hole and having one side fixed with an insert rod to be inserted through said insert hole of said fixing base, said regulating button assembled on the outer wall of said housing and provided with a connecting rod extending into the interior of said housing, said connecting rod of said regulating button bored with a lengthwise insert hole for said insert rod of said blocking member to be inserted therein.  
   
   
       3 . The steam structure for a steam roaster oven as claimed in  claim 1 , wherein said holding tray is covered with a cover plate bored with an insert hole aligned to said draining hole at the bottom of said housing and located on the other of said accommodating chambers of said holding tray.
